Can you check this error ?
Based on the error, you're trying to get/change the properties of the variable "directionalTextHelper," which hasn't been initialized. You may want to initialize it, first.

I was doing changes in YoungAndroidPalettePanel and there is no variable "directionalTextHelper" 
Something you have changed in the YoungAndroidPalettePanel has triggered this exception. Use git to check your changes in that method. In particular, it looks like you could be calling selectCategory somewhere before the categories are initialized. Since your sources aren't available I can't really advise further.

Sir @ewpatton, I added this code inside selectCategory method.
mLabel.setText(currentCategory.getName());
Right, so potentially your issue is that if currentCategory is not yet initialized it will fail here. Remember that GWT converts the code into Javascript and as part of that process it inlines some of these simple methods like getName.

Sir @ewpatton , Should I use this code where category is parameter.
`mLabel.setText(category.getName());`
